A ballet based on a video game? It exists and is currently online.
I lack the vocabulary to comment on the dance, though I’ve sat through enough Nutrcracker’s to know you can stage an exciting sword fight. Adding a Barbarian woman to the heroes team helps balance out the distressed damsels. I was really hoping the Dragon Lord would turn into a giant dragon puppet. (Spoiler: He doesn’t).
The most successful element of the project appears to be Koichi Sugiyama’s score. He’s composed gorgeous video game music since the 1980's and it lends itself well to the stage.
